Paper container
A paper container includes a base disk and a peripheral wall having a ledge extending from a bottom edge of the peripheral wall to engage with a bottom face of the base disk, a side wall integrally formed adjacent to the ledge and having an inner surface to engage with a peripheral edge of the base disk, a knurl formed between the ledge and the side wall for engagement with a surface and a lip ring formed on a top edge of the peripheral wall such that an annular space is formed between the base disk and the peripheral wall.
1. Field of the Invention
The present invention relates to a paper container, and more particularly to a container made of paper and having a central disk-like sheet and an annular sectorial side face attached to a peripheral edge of the central sheet.
2. Description of Related Art
A conventional paper container (40), as shown in
However, after a paper container (40) of this kind is formed, forming the patterns (41) on the side walls of the paper container (40) increases the manufacture and labor cost. Besides, because the paper container is made from a single paper sheet (30), the base ring, which later on is held by a user, has poor heat isolation such that the user can not hold the paper container if the paper container is filled with a hot content.
To overcome the shortcomings, the present invention tends to provide an improved paper container to mitigate the aforementioned problems.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide an improved paper container composed of a base disk and an annular peripheral wall with a ledge extending out from a base ring which has a knurl formed on a joint between the ledge and the side wall to be engaged with a surface, such that the user is able to hold the paper container by the knurl and a lip ring formed on a free edge of the peripheral side wall.
Another objective of the present invention is that before the paper container is formed, the peripheral wall has a cutout defined in a portion of the peripheral wall so that when two distal ends of the peripheral wall are connected to one another, a conical shape is formed for connection with the base disk.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
With reference to
The base disk (10) is a circular disk made of paper.
The peripheral wall (20) has a ledge (25) formed on a bottom edge of the peripheral wall (20) and extending in a first direction, a lip ring (21) formed on a top edge of the peripheral wall (20) and extending in a second direction opposite to the first direction of the ledge (21) and a knurl (23) formed on a joint between the ledge (21) and the side wall (22) of the peripheral wall (20). A cutout (A) is defined between two distal ends of the peripheral wall (20).

It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
Claims
1. A paper container comprising:
- a base disk; and
- a peripheral wall having a ledge extending from a bottom edge of the peripheral wall to engage with a bottom face of the base disk, a side wall integrally formed with and adjacent to the ledge and having an inner surface to engage with a peripheral edge of the base disk, a knurl formed between the ledge and the side wall for engagement with a surface and a lip ring formed on a top edge of the peripheral wall such that an annular space is formed between the base disk and the peripheral wall.
2. The paper container as claimed in claim 1, wherein a bend is formed on the peripheral edge of the base disk to engage with the inner surface of the side wall of the peripheral wall.
3. The paper container as claimed in claim 2, wherein the ledge extends in a first direction and the lip ring extends in a second direction opposite to the first direction.
4. A paper container comprising:
- a base disk having a knurl formed adjacent to a peripheral edge of the base disk;
- a peripheral wall having a ledge formed on a bottom edge of the peripheral wall, a side wall integrally formed with and adjacent to the ledge and a lip ring formed on a top edge of the peripheral wall, such that an engagement between an outer surface of the side wall and an inner face of the peripheral edge of the base disk combines the base disk and the peripheral wall.
5. The paper container as claimed in claim 4, wherein a bend is formed on the peripheral edge of the base disk for engagement with the outer surface of the side wall.
6. The paper container as claimed in claim 5, wherein an annular space is defined between the base disk and the peripheral wall.
